PROBLEM POSSIBLE CAUSE(S) CORRECTIVE ACTION
CONDENSATION
1. Filling the new water heater for the fi rst
time
2. Moisture from the products of combustion
3. Water dripping from blower assembly
4. Undersized water heater
1. Normal operation: the condensation
should disappear after heater warms up
2. Normal operation: the condensation
should disappear in time
3. Install condensate hose to drain port on
the rubber coupling
4. Install adequate heater
COMBUSTION ODORS
1. Air inlets blocked
2. Insuffi cient air
3. Flue
clogged
4. Heater installed in a confi ned area
5. House too tight
1. Unblock inlet air openings
2. Provide fresh air ventilation to the water
heater
3. Clean, locate source and correct
4. Provide fresh air ventilation to the water
heater
5. Provide fresh air ventilation to the water
heater
SMOKING AND CARBON
FORMATION
1. Air inlets blocked
2. Insuffi cient air
3. Low gas pressure
4. Orifi ce too large
5. Flue
clogged
6. Defective gas control valve/thermostat
7. Heater installed in a confi ned area
1. Unblock inlet air openings
2. Provide ventilation to water heater.
Check fl ue way, fl ue baffl e and burner
3. Check with gas utility company
4. Replace with correct orifi ce (see rating
plate)
5. Clean, locate source and correct

7. Provide fresh air ventilation
UNABLE TO LIGHT
THE BURNER
1. Air in gas line
2. Pressure
switch
3. Blocked exhaust
4. Wire connection
5. Defective gas control valve/thermostat
1. Purge the air from gas line

3. Check vent pipe for blockage
4. Check wire connections
5. Replace the gas control valve/
thermostat
SIZZLING, RUMBLING
NOISE
1. Scale and sediment
2. Condensation dripping on burner 1. Drain/fl ush-provide water treatment if
needed
2. Refer to “Condensate” section
WATER LEAKAGE
1. Condensation
2. Dripping Temperature & Pressure Relief
Valve
3. Drain valve dripping/leaking
4. Tank
Leak
1. Refer to “Condensate” section
2. Refer to “Temperature & Pressure Relief
Valve” section
3. Back flush to clean- out sediment,
replace if necessary.
4. Check “Leakage Checkpoints”
BLOWER WILL
NOT START
1. No power to unit
2. Thermostat set too low
3. Defective air pressure switch
4. Defective
blower
5. Disconnected or loose wire
6. Control locked out
